Yarn pack



H. BUDDECKE YARN PACK Filed Aug.

Oct. 30, 1962 ite ttes The invention relates to yarn packs consisting of a spirally coiled yarn strip of yarn windings scale-like overlapping each other, which has to take the place of the usual yarn skeins in order to save the buyer, previous to working up of the yarn, from unwinding the skeins to balls.

The yarn-strip-roll is on the outside embraced by the last spiral coil of a rolled up separating leaf strip or by a particular leaf of paper cr the like for holding it together. Further on, the yarn-strip-roll is enclosed by a protecting jacket in the form of a card board box, a foil bag or the like as a protection against inuences of all kinds from the end of which the yarn thread can be drawn off through a thread-opening.

As it is desirous that the yarn can be inspected thoroughly and without hindrance and can be handled like the usual yarn skeins, contrivances have been proposed for entirely or partly drawing the yarn strip roll out of the closeable opening of its jacket in order to lay open at least the front face of the yarn striproll up to which hitherto the embracing was located.

The invention aims at a substantial improvement of the laying open of yarn portions.

To this end, according to the invention, the yarnstrip-roll is held together in its spiral form only along a small part of its width by embracing means with the unembraced part of the yarn strip together with its yarn returns being completely free so that they can be spread out like a rosette.

On spreading out the single yarn windings the yarnstrip-roll assumes a mushroom-like form with a surface which is by a multiple larger than the section of the roll itself so that the possibility for the buyer to inspect the yarn will be considerably increased. The yarn thread can be drawn out of this rosette without the danger of entanglement as the embraced part of each winding retains its position unchangeable in the whole roll. Preferably, the width of the embracing will be chosen narrower than the half of the width of the yarn strip in order to get, on the one hand, the yarn rosette as large as possible and to obtain, on the other hand, a friction resistance of the thread produced by the embracing means as small as possible.

This arrangement obtains particular importance when the yarn strip roll is provided with a protecting jacket, for instance in the form of a bag consisting of transparent plastic foil. in this case the roll can be optionally drawn out and spread out. By shifting' it back into the protecting jacket it will be restored into its compact form. The embracing can be situated, instead at an end, also at the middle zone of the yarn-strip-roll or can be formed by two middle embracing strips spaced from each other. In the latter case, after taking out the yarn-strip-roll, two rosettes may be formed.

With the known yarn packs of the mentioned kind the thread is usually drawn out with its inner thread end, while the outer end is fixed. Frequently it is desired t simultaneously work up two threads. For this case it will be provided for that the inner end as well as the outer end can be drawn out at the same time. When the wound up thread is composed by half of two diiferent kinds of yarn, two different yarn threads can be worked up at the same time. In the above mentioned arrangement of forming a yarn rosette at each end of the yarn-strip-roll the rice two threads can be drawn out, each from one of the ends of the yarn-strip-roll.

With known yarn packs the thread returns and the edges of separating leaf strip or the like each are arranged in a plane. By an arrangement deviating from a plane the forming of the yarn-rosette can be considerably improved.

Further, with the known yarn packs maintaining the correct mutual position of the single yarn windings until the drawing oif of the last yarn is attained in that the spirally rolled with separating leaf strip extends with one of its edges beyond the yarn winding strip, its spiral coils here being sticked with each other, thus that a separating leaf skeleton is formed which prevents the yarn-strip-roll from collapsing after a greater quantity of yarn has been drawn out.

In order to maintain the rest of the yarn-strip-roll in its correct form in the described form of embodiment (in which a separating leaf skeleton of this kind is not provided for and a separating leaf strip, after all, can be wanting) special tightening means are used which keep the spiral-roll under tension either from inside to outside or from outside to inside, so that the embraced rest of the roll always retains its proscribed position.

A particularly usable embodiment of the yarn pack consists in that the yarn winding strip is divided into groups of yarn windings connected with each other, each being enclosed by the separating leaf strip and can be drawn out one after the other.

Further features of the invention result from the following description of an example of embodiment of the invention.

in the accompanying drawing:

FIG. l is a yarn-strip-roll enclosed in a protecting bag.

FIG. 2 is a yarn-strip-roll in the form of a rosette taken out of its protecting jacket.

FlG. 3 is a perspective view of the end of a yarn-striproll embraced by a tightening means and wit-h a guiding strip.

FIG. 4 is a part of a middle section of a yarn-strip-roll.

FIG. 5 is a front-view of a yarn-strip-roll with shuttingup-tongues.

FIG. 6 is a front-view of the yarn-strip-roll with a tightening means in its tensioned state.

FlG. 7 is a corresponding View in the de-tensioned state of the tightening means.

FIG. 8 is a yarn pack with a middle embracing, with which the yarn thread can be drawn oi from both of the ends.

FIG. 9 is a yarn pack with two middle embracing strips.

FIG. l0l is a yarn pack with a suspending device.

FIG. ll is a yarn pack having adjacent coils of the separating leaf strip glued with each other from space to space.

FIG. l2 is an unrolled yarn winding strip together with an unrolled separating leaf strip.

In the example of embodiment according to FIGS. l and 2- the yarn winding strip l, spirally wound up with or -without a separating leaf strip, is held together at one of its ends by a broad embracing strip 2 which can be represented too by the last coil of the separating leaf strip. The part of the yarn windings not 'being in the reach of the embracing strip 2 lies quite free and, Iafter taking the yarn strip roll out of the protecting bag 3, is enabled to be spread out like a rosette according to the manner represented in FIG. 2, so that the greater part of the wound up yarn `is oifered for Iview-ing and handling to the buyer.

In order to perfect the form 'of the rosette and to give it a fully equable and pleasing `form the yarn returns of the single windings can be arranged, under circumstances,

instead in a plane deviating from a plane according to a distinct pattern as represented in FIG. 4. The free lying yarn windings also `can be differently formed, for instance waved. Further, the embracing strip 2 or the rolling up separating leaf strip 4 can be waved at the one edge 5 as at 5 (FIG. l) in order to inuence therewith the manner of spreading out the single yarn windlngs.

In the example of embodiment according to FIG. 8 the yarn-strip-roll is provided in the middle zone only with an embracing 'means 2. After taking out the yarnstrip-roll of the protecting bag 2 two yarn rosettes can be formed here.

In the example of embodiment according to FIG. 9 two strips 2 are used -as embracing means which are arranged in the lmiddle part of thel yarn-strip-roll spaced from each other and leaving completely 4free three zones of yarn windings havingr about the same lengths. Here also, after the yarn-strip-roll is drawn out of the protecting bag, two yarn rosettes can be formed.

As a skeleton-like form of the separating leaf strip is not provided for, particular provisions have to be made in order to maintain the rest of the yarn strip roll in its prescribed `form and to avoid entanglements, after a greater yarn quantity has been drawn out.

To this end particular tension means in form of elastic strips are provided which will be put into the hole formed by the innermost coil of the separating leaf strip or which can be arranged around the louter coil of the yarn strip, the object of these means is to press together the yarnstrip-roll from inside to outside or `from outside to inside. Such tension strips 6 which are introduced into the inner hole 7 will be apparent from the FIGS. 3, 6 and 7. The tension strip may consist of any elastic material `and has, in its tensioneid state (FIG. 6), either S-like or spiral-like Shape according to the maintaining power of a clock. FIG. 7 shows the tension strip 6 in its untensioned state.

In order to dispense with such tension means particular provisions have to be made against entanglement of the inner spiral coils of the yarn winding strip. This will be effected -by the arrangement of particular guiding strips 8 (FIG. 4) which are enveloped in the y-arn winding strip and which register with the yarn returns 8 of the inner spiral windings or project somewhat beyond them y strip in that the edges of the latter are laccordingly stepped.

The tension strip 6 can similarly be connected with the separating leaf strip 4, for instance glued, to it.

Whilst usually the inner end 1.0A (FIG. 3) of the wound up thread will be drawn out of the pack, the disposition can be m-ade that at the same time the outer end l1, hitherto mostly being fixed, can be drawn out, so that two threads can be worked up simultaneously. In the embodiment according to FIG. 8 in which the protecting bag 3 comprises two closable ends, the embracing means 2 can be xed to the protecting fbag, for instance, by gluing. The two thread ends 1t) and 11 then can be drawn olf to the pack in different directions. When each half of the coiled up thread consists of a different kind of yarn, two threads of different kind of yarn can also simultaneously be drawn out from the same pack and Worked up.

The separating leaf strip 4 (FIG. 5) or the guiding strip 8 can be provided with projecting tongues 12 at the end of the yarn-strip-roll opposite the drawing out end. The tongues can be bent together lin `a manner represented in FIG. 5 and can be pasted or otherwise connected with each other in order to maintain the coiled form.

The tongues 12 can serve in a folded together and perforated form, as is represented in FIG. 10, as hanging up means for hanging up the pack with ti e closable opening of the protecting pack downwardly directed.

A particular usable, easily feasible embodiment which fulfills the effect of a separating leaf skeleton is shown by the FIGS. ll and l2. Here the yarn Winding strip is divided into groups l lof yarn windings connected with each other, each embraced by thc separating leaf strip and can be drawn out one after the other. In the embodirnent, represented in FIG. ll, adjacent coils of the separating leaf strip are glued with each other in spaces at the spots i3 between the single yarn str-ip groups 14. Between the yarn winding groups intermediate spaces are arranged which will be bridged by a bridging thread part l5. This bridging thread part is located on the side of the separating leaf strip i which is directed towards the drawing lout end of the yarn strip roll.

The separating leaf strip may consist of a suitable plastics having wide meshes or being net-like perforated permitting a free passing of gaseous vapours and fluids so that the yarn-strip-roll after being prepared can be correspondingly heated, for instance impregnated.

ln order to lead the thread end located in the protecting bag outwards through the thread open 17 (FIG. l) in the thread guide member i8 of the closable end of the protecting bag, it is only necessary to suddenly and laterally depress the protecting bag. The current of air passing thereby through the thread opening taking with it the thread end outwardly. To this end, however, the thread opening i7 has to be sufficiently large and suicient free air has to be in the bag containing the yarn-strip-roll.
